5. ADJUSTMENTS
Obtaining the maximum performance from your suspension
system depends on using the correct settings and making
the proper adjustments. This section describes how to
properly set and make adjustments to your Marzocchi
suspension system.
In order to fi nd the best settings for you, you will need to
try several times to understand where and how to make
adjustments.
When doing so, please ride in an open area, free from traffi c,
obstacles and other hazards.
The best settings not only depend on the Motorcycle frame
geometry, the rider’s weight and the types of trail or obstacles,
but also on many other personal factors connected with your
riding style.
Therefore, it is not possible to provide you with objective
information concerning your desired settings.
Changing the settings on your suspension system must be done
on only one adjuster at a time, taking note of the modifi cations
you carry out and the improvements you obtain.
WARNING!
During the setting operations, never force the adjusters
past their limits.

5.1 Initial suspension bottoming adjustment
Optimal spring hardness is that which reaches the required
SAG, in other words, the suspension is lowered solely due to
the rider’s weight.
How to measure SAG
In order to measure the SAG, you only need to carry out the
following steps:
Pick up the front of the motorcycle so that the wheel is off
the round, measure the part of the leg between the edge of
the wheel axle clamp and the dust seal, then take note of
the value as “H1”.
Repeat the measurement with the motorcycle in a vertical
position with both wheels on fl at round then take note of the
value as “H2”.
SAG = H1 - H2
The optimal SAG is equal to 25 - 40 mm (based on the
motorcycling activity).
When you have a value that is lower than recommended, you
must reduce the pre-load or replace the spring with a “softer”
one to obtain the best performance from the suspension, vice
versa when the value is higher it is necessary to increase the
pre-load or install a “harder” spring.
-----
5.2 Spring preload adjustment
The spring preload adjustment can be done following the
procedure here below described, after disassembly of the
cartridge set from the fork’s leg interior (see par. 4.6):
Slide the preload adjustment set (7) towards the cartridge
lower edge, so that the metal ring seat becomes
uncovered.
Using a small fl at-tip screwdriver remove the metal ring (26)
from its seat.
By changing the metal ring position as to the seats, you
will preload the spring more or less, with 5 mm- increase/
decrease (see fi gure).
During extraction and re-insertion of the metal ring, be very
careful not to damage the components.
WARNING!
During extraction and re-insertion of the metal ring,
be very careful not to damage the components. If
the cartridge and more specifi cally the metal ring are
damaged, even in a light way, do not use the fork in any
case and immediately contact an authorized Marzocchi
service center. Do not alter the metal ring.
